New Patents Emerge for non-GPS Inside geo-location

In late 2006, Rhoads co-founded ZuluTime, to apply work he was doing at the time in communication synchronization between satellites to terrestrial, wireless networks. Since then, the startup has focused on developing position, navigation and timing technologies (in other words, geolocation) for indoor wireless networks.
The patent ZuluTime announced today is part of a suite of patents currently awaiting approval (Rhoads tells me he expects an eventual number in the high two-digit range) that will allow companies using a ZuluTime software-enabled wireless network to locate and position smartphones (and other networked devices) with a high degree of accuracy, particularly in environments subject to interference and distortion.
The patent, also known as “US Patent #7,876,266″, or “Harmonic Block Technique for Computing Space-Time Solutions for Communication Networks”, sounds like something out of Nikola Tesla’s notebook — and repeating the title out loud may give you a minor aneurysm. But, in lay-speak, the technology ZuluTime has developed (and is developing) is a natural extension of GPS and geolocation technology. Your GPS-enabled phone may be able to guide you, say, to a store’s location, but once you are inside, you are as good as invisible. So, the startup has created a software solution that replaces GPS for indoor navigation, by making indoor wireless networks location-aware.
